What about similarly populated cities?
In new street additions, Debark and Afamolla both built increasingly disconnected streets over time, while Kalpetta built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Debark and Afamolla both became progressively more disconnected, while Kalpetta became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Debark and Kalpetta have been converging in their street-network character since 1975.
